Abstract

A new numerical scheme for the solution of the constant density acoustic wave equation is derived. The scheme is based on recursive second derivative operators which are derived by an L fit in the spectral domain. The use of recursive derivative operators enables to extend the forward modeling to shorter wavelengths. An example of reverse time migration of a synthetic dataset shows that the numerical dispersion can be significantly reduced with respect to schemes based on finite differencing.
